[Gretl-devel] Cumulated values of matrix with missing values

Hi all, I just would like to ask whether this behavior is actually expected: <hansl> matrix m = {1, NA; 2, 3} print m eval cum(m) ? print m m (2 x 2) 1 nan 2 3 ? eval cum(m) 1 nan 3 nan </hansl> I expected the entry (2,2) to be 3 as this is the first valid value of the 2nd column. The help does not say anything on how missing values are handled on the function reference: http://gretl.sourceforge.net/gretl-help/funcref.html#cum Thanks, Artur
